636851 ÷ 70 
Our goal is to divide 636851 by 70.

Let's proceed to step 1:
The number 70 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 70

Advancing to step 2:
If we divide 63 by 70, we get 0 and a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Include the next digit (6) from the dividend after 63, then repeat: 636 / 70

Going ahead to step 3:
70 goes into 636 9 times with a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 630 away from 636, we end up with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 70

Moving on to step 4:
When dividing 68 by 70, we get 0 with a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 90.0
The remainder is 68 after subtracting 0 from 68.
Take the next digit (5) from the dividend and append it to 68, then repeat: 685 / 70

On to step 5:
685 divided by 70 is 9 with a remainder of 55.
The number 9 becomes the next digit in our result. 
Result so far: 909.0
Subtracting 630 from 685 leaves us with 55.
Bring next digit (1) of the dividend behind the 55 and repeat the process: 551 / 70

Step 6:
The number 70 fits into 551 7 times, leaving a remainder of 61.
Put 7 as the next digit of the answer. 
Result so far: 9097.0
Subtract 490 from 551 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 7:
610 divided by 70 is 8 with a remainder of 50.
The number 8 becomes the next digit in our result. 
Result so far: 9097.8
If we take 560 away from 610, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 8:
70 can be fit into 500 7 times, resulting in a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 9097.87
The remainder is 10 after subtracting 490 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
When dividing 100 by 70, we get 1 with a remainder of 30.
The next digit of our result is 1. 
Result so far: 9097.871
Subtracting 70 from 100 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
When dividing 300 by 70, we get 4 with a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 9097.8714
Subtracting 280 from 300 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 11:
When dividing 200 by 70, we get 2 with a remainder of 60.
The next digit of our result is 2. 
Result so far: 9097.87142
Subtracting 140 from 200 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 12:
If we divide 600 by 70, we get 8 and a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 9097.871428
Subtract 560 from 600 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 13:
When dividing 400 by 70, we get 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 9097.8714285
If we take 350 away from 400, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 14:
When dividing 500 by 70, we get 7 with a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 9097.87142857
Subtracting 490 from 500 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 9097.87142857 and a remainder of 1e-08.
